1. In the Gram Stain procedure, which component acts as the mordant?

• A. Crystal violet
• B. Methyl alcohol
• C. Iodine
• D. Safranin

Correct answer: C

Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.

2. The most accurate reading for a temperature is done:

• A. Orally
• B. Aurally through a clean canal
• C. Rectally
• D. Axially

Correct answer: B

Rationale: Aural readings are done through the ear canal. The tympanic membrane shares a blood supply with the hypothalamus, the brain area that regulates body temperature. Taking the temperature aurally through a clean canal ensures an accurate reading. Choice A (Orally) is not the most accurate method for temperature measurement as it can be affected by external factors like drinking hot or cold liquids. Choice C (Rectally) is invasive and less practical for routine temperature monitoring. Choice D (Axially) is not a standard method for temperature measurement and may not provide accurate results.

3. The client often sighs and says in a monotone voice, 'I'm never going to get over this.' When encouraged to participate in care, the client says, 'I don't have the energy.' These cues are suggestive of which nursing diagnoses? Select all that apply.

• A. Hopelessness
• B. Power
• C. Interrupted sleep pattern
• D. Disturbed self-esteem

Correct answer: A

Rationale: A nursing diagnosis involves clinical judgment about a response to a health problem. In this scenario, the client's expressions of feeling overwhelmed and lacking energy indicate feelings of hopelessness and powerlessness. While fatigue is mentioned, there is no direct evidence to support an interrupted sleep pattern, making option C incorrect. Similarly, disturbed self-esteem and self-care deficit are not evident from the given cues, making options D and E incorrect.

4. A client is diagnosed with ariboflavinosis. Which of the following foods should the nurse serve this client?

• A. Citrus fruits
• B. Milk
• C. Fish
• D. Potatoes

Correct answer: B

Rationale: Ariboflavinosis is a vitamin B-2 deficiency. Symptoms may include cracks around the mouth, inflammation of the tongue, or light sensitivity. Foods rich in vitamin B-2, like milk, liver, green vegetables, or whole grains, are recommended. Citrus fruits (choice A) are good sources of vitamin C, not B-2. Fish (choice C) is a source of protein and omega-3 fatty acids but not a significant source of vitamin B-2. Potatoes (choice D) are a source of carbohydrates but do not provide high levels of vitamin B-2.

5. The body system that functions to maintain fluid balance, support immunity, and contains the spleen is the:

• A. Lymphatic System
• B. Digestive System
• C. Urinary System
• D. Respiratory System

Correct answer: A

Rationale: The Lymphatic System is responsible for maintaining fluid balance and supporting immunity. It contains organs like the spleen, tonsils, thymus, lymph nodes, and lymph vessels. The spleen, a part of the lymphatic system, plays a crucial role in filtering blood and storing blood cells. The Digestive System is primarily involved in the breakdown and absorption of nutrients, not fluid balance or immunity. The Urinary System is responsible for filtering waste products from the blood and regulating fluid balance, but it does not support immunity or contain the spleen. The Respiratory System is focused on gas exchange and oxygenating the blood, not fluid balance or immunity.
